  • sitting path 82 is a path configured from a curved path from second position P2 to third position P3 and a straight path from third position P3 to first position P1.
  • Path setting section 62 in a case in which a standing operation or a sitting operation is input as an operation request, sets either of standing path 81 or sitting path 82 as a reference path based on the current state including the current position of holding member 21.
  • Driving control section 63 moves holding member 21 based on the set reference path. Specifically, driving control section 63 synchronizes operation of raising and lowering section 30 and oscillating section 40 and controls operation of driving device 23 such that holding member 21 is moved along the reference path.
  • control device 60 for example, in a case in which sitting switch 52 of controller 50 is pushed, controls movement of holding member 21 along standing path 81 in addition to controlling movement of holding member 21 along sitting path 82. Similarly, this applies when standing switch 51 of controller 50 is pushed. In this manner, the purpose of executing operation processing of holding member 21 based a movement path not corresponding to the requested operation is so that holding member 21 is moved along a movement path corresponding to the usage state of assistance robot 1.
  • path setting section 62 in a case in which standing switch 51 or sitting switch 52 is pushed so as to input a requested operation, sets the reference path of the requested operation based on at least one of the current position and the current angle of holding member 21 that are included in the current state of holding member 21.

  • specified position Pr is a position of holding member 21 in the front-rear direction with respect to base 10 and is set based on the angle of holding member 21.
  • driving device 23 of the embodiment is configured to move holding member 21 in the front-rear direction and to rotate holding member 21 around oscillation shaft center 32a by rotating arm 42 of oscillating section 40. That is, as shown in the lower section of fig. 5 , oscillating section 40 oscillates holding member 21 to be at an angle ⁇ regulated with respect to the position of holding member 21 in the front-rear direction. As shown in figs. 2 and 3 , angle ⁇ of holding member 21 is an angle with respect to a vertical axis, and increases as holding member 21 moves forward.
  • the buttock portion Mb of the care receiver M is raised from the seat of chair and their body weight is leaning towards supporting device 20.
  • the position of holding member 21 in the front-rear direction corresponding to specified angle ⁇ t of holding member 21 in the above state is set as the above specified position Pr.
  • Included in the multiple areas represented by area information 73 are standing priority area Ar and sitting priority area As generated by demarcating the moving region Rn of holding member 21 in the front-rear direction via specified position Pr.
  • Standing priority area Ar is an area for which path setting section 62 gives priority to setting standing path 81 as the reference path in a case in which holding member 21 is positioned in that area.
  • Standing priority area As is an area for which path setting section 62 gives priority to setting sitting path 82 as the reference path in a case in which holding member 21 is positioned in that area.
  • standing priority area Ar is positioned to the rear of sitting priority area As.
  • Reference path setting processing by path setting section 62 of control device 60 is described below with reference to figs. 5 to 8 .
  • Reference path setting processing is executed when, for example, standing switch 51 or sitting switch 52 of controller 60 is pushed so as to input a standing operation or a sitting operation as a requested operation. Note that, when raising switch 53 or lowering switch 54 of controller 50 are pushed, because operation of raising and lowering section 30 is controlled without using the reference path, reference path setting processing is not executed.
  • path setting section 62 of control device 60 first, determines whether the requested operation and the previous operation that moved holding member 21 to the current position are the same (step 11 [hereinafter, "step” is abbreviated to "S"]). For this, path setting section 62 acquires information representing the previous operation that is temporarily memorized in memory section 61. This information includes, as the previous operation, a standing operation, a sitting operation, a raising operation, and a lowering operation. Also, in a case in which information representing the previous operation is not memorized, path setting section 62 determines that the power switch (not shown) has just been turned on, and that the previous operation was turning on the power.
  • Path setting section 62 when determining that the previous operation and the requested operation are the same (S11: yes), sets the movement path of holding member 21 corresponding to the requested operation as the reference path regardless of the current state of holding member 21 (S15). Then, the same operation as the previous operation is restarted by controlling driving control section 63.
  • This operation assumes a case in which, for example, an operator released standing switch 51 during standing operation, and then pushed standing switch 51 again (patterns N11 and N12 in fig. 7 ).
  • path setting section 62 determines whether the previous operation was any of the raising operation, the lowering operation, or turning on the power (S12). If the previous action is determined to be one of the raising operation, the lowering operation, or turning on the power (S12: yes), path setting section 62 sets the movement path of holding member 21 corresponding to the requested operation as the reference path regardless of the current state of holding member 21. Then, holding member 21 is moved from the current position and the current angle along the reference path corresponding to the requested operation by control of driving control section 63 (patterns N15 and N16 in fig. 7 and patterns N25 and N26 in fig. 8 ).
  • Path setting section 62 in a case in which the previous is none of the raising operation, the lowering operation, or turning on the power (S12: no), that is, the requested operation is the standing operation and the previous operation was the sitting operation, or the requested operation was the sitting operation and the previous operation was the standing operation, acquires the current state of holding member 21 (S13). In the embodiment, path setting section 62 acquires current position Pc of holding member 21 as the current state.
  • path setting section 62 selects one of standing path 81 or sitting path 82 based on the current position of holding member 21 and area information 73, and sets that path as the reference path of the requested operation (S14). Specifically, if the area to which current position Pc of holding member 21 belongs is standing priority area Ar, standing path 81 is set as the reference path of the requested operation. On the other hand, if the area to which current position Pc of holding member 21 belongs is sitting priority area As, sitting path 82 is set as the reference path of the requested operation.
  • standing path 81 is set as the reference path (pattern N13 in fig. 7 ).

  • sitting path 82 is set as the reference path (pattern N22 in fig. 8 ).
  • the reference path of the requested operation is set as the movement path (sitting path 82) corresponding to the requested operation.
  • standing path 81 is set as the reference path (pattern N21 of fig. 8 ).
  • the reference path of the requested operation is set as the movement path (standing path 82) that does not correspond to the requested operation (sitting operation).
  • path setting section 62 selects a movement path that does not correspond to the requested operation and sets that movement path as the reference path in accordance with the current state of holding member 21 (pattern N14 of fig. 7 and pattern N21 of fig. 8 ). Accordingly, during subsequent operation, holding member 21, instead of being moved along the movement path corresponding to the requested operation, is moved along a movement path that does not correspond to the requested operation (that is, the movement path corresponding to the previous operation).
  • Such control means that operation according to the desire of the operator is performed while considering safety based on the loaded state of the body weight of care receiver M with respect to holding member 21 and the like.
  • holding member 21 is moved from the current position and the current angle along the reference path by control of driving control section 63. In this manner, assistance robot 1 moves holding member 21 along a movement path in accordance with various usage states, so as to assist a standing operation and a sitting operation of care receiver M.
  • Assistance robot 1 is provided with: base 10, holding member 21 configured to hold an upper body of care receiver M; driving device 23 configured to move holding member 21 in an up-down direction and a left-right direction of base 10; and control device 60 configured to control operation of driving device 23.

  • path setting section 62 when determining that the requested operation and the previous operation that moved holding member 21 to current position Pc are the same (S11: yes), sets the movement path of holding member 21 corresponding to the requested operation as the reference path regardless of the current state of holding member 21 (S15).

  • a movement path corresponding to the requested operation (standing path 81 if the requested operation is the standing operation; sitting path 82 if the requested operation is the sitting operation) is set as the reference path without switching the reference path based on the current state of holding member 21.

  • specified position Pr may be configured to be set in addition to or instead of the angle of holding member 21. Accordingly, standing priority area Ar and sitting priority area As can be demarcated, for example, along a boundary line inclined with respect to the vertical axis.
  • multiple specified positions, Pr1 and Pr2 may be set in the front-rear direction of holding member 21 to demarcate three areas.
  • included in the multiple areas is intermediate area Am positioned between standing priority area Ar and sitting priority area As.
  • specified positions Pr1 and Pr2 are positions in the front-rear direction of holding member 21 corresponding to, for example, first angle ⁇ t1 and second angle ⁇ t2 of holding member 21.
  • intermediate area Am when holding member 21 is positioned in that area, may be an area for which path setting section 62 gives priority to setting the movement path of holding member 21 corresponding to the previous operation as the reference path.
  • path setting section 62 gives priority to setting the movement path of holding member 21 corresponding to the previous operation as the reference path.
  • a movement path (standing path 81) that does not correspond to the requested operation (sitting operation) is set as the reference path. According to such a configuration, compared to a case of demarcating two priority areas, it is possible to set the reference path in more detail in accordance with the current state.
  • driving device 23 is configured from raising and lowering section 30 that moves in an up-down direction with respect to base 10, and oscillating section 40 that oscillates holding member 21.
  • driving device 23 may come in various forms so long as it supports holding member 21 to be movable with respect to the up-down direction and the front-rear direction of the base, and moves holding member 21 along multiple different movement paths.
  • oscillating section 40 in addition to rotating arm 42 and rotating oscillation main body 41 around an axis while moving oscillation main body 41 in the front-rear direction, for example, may be configured to support oscillation main body 41 by a rail inclined in the front-rear direction on an upper section of raising and lowering section 30. With such a configuration, due to the movement of oscillation main body 41 along the rail, it is possible to move holding member 21 attached to oscillation main body 41 in the front-rear direction and to make holding member 21 inclined.
  • driving device 23 may be configured from a rotation member provided on base 10 that rotates around an axis that is parallel to the left-right direction, and an extending arm that is provided on the rotation member and is extendable in the diameter direction of the rotation member. Also, driving device 23 may be configured including a first rotation member that rotates around a shaft parallel to the left-right direction, and a second rotation member that is provided on the first rotation member and that rotates around an axis parallel to the rotation axis of the first rotation member.
  • holding member 21 is able to move in the up-down direction and the front-rear direction of base 10, and is able to move in accordance with multiple movement paths. Also, when moving holding member 21 along multiple movement paths, by setting the reference path of the requested operation based on the current state of holding member 21, similar effects to the main embodiment are achieved.
